California Cosmetology Written Exam flashcards

A mirror consultation is a technique where the cosmetologist and client face a mirror together so the stylist can point to specific facial features and head areas to clarify the planned service.

• Provides direct visual reference on the client's own features
• Reduces miscommunication before cutting/coloring begins
• Often combined with photos or swatches for further clarity

Memory trick: Mirror consultation = 'Show, don't just tell' — point it out in the reflection.

The minimum time an implement must stay immersed in an EPA-registered hospital disinfectant to be considered properly disinfected.

• CA requires full immersion, not just wiping
• Standard minimum contact time is 10 minutes
• Implement must be pre-cleaned of debris before immersion
• Disinfectant must be changed daily or when visibly contaminated

Memory trick: 'Ten minutes to shine' — implements soak like tea bags.

A chronic, non-contagious vascular skin disorder causing facial redness, flushing, and visible blood vessels, often triggered by heat and certain products.

• Not contagious
• Triggered by heat, sun, spicy food, harsh products
• Requires gentle products and avoidance of heat/irritants

Memory trick: ROSacea = ROSy cheeks that flare with heat—go gentle.

A powder lightener formulated with an added activator/booster for maximum lift, intended for use away from the scalp due to its strength and burn risk.

• Activators increase the lightening power of powder bleach
• Off-scalp formulas are too strong/irritating for direct scalp contact
• Used for techniques like balayage, foiling, or highlighting away from the scalp

Memory trick: Off-scalp lightener + booster = powerful, but keep it OFF the scalp.

The warmth or coolness of a hair color, expressed through terms like gold, copper, ash, or violet.

• Tone is separate from level (lightness/darkness)
• Warm tones: gold, copper, red, orange
• Cool tones: ash, violet, blue

Memory trick: Level = how light/dark; Tone = how warm/cool.

A product used to replace missing pigment in over-lightened or damaged hair prior to applying a final target color, ensuring true, even color results.

• Restores warm underlying tones lost from lightening
• Equalizes porosity across the hair shaft
• Applied before the final color formula in corrective work

Memory trick: Filler refills the missing warmth before painting the final color.

Elasticity testing measures how much hair can stretch and return to its original length without breaking; normal dry hair stretches about 20%, while normal wet hair stretches about 50%.

• Dry hair: ~20% stretch is normal
• Wet hair: ~50% stretch is normal
• Breaking before these percentages signals low elasticity/damage

Memory trick: Dry stretches a fifth (20%), wet stretches half (50%) — water adds flexibility.

A small test application of a new wax or product on an inconspicuous skin area, monitored for at least 24 hours, to check for allergic reactions before performing a full service.

• Used when introducing new products or on new clients
• Applied to inconspicuous skin area, not sensitive facial zones
• Monitored for redness, itching, swelling before proceeding

Memory trick: 'Test small before you go tall (full service)'

A hair shaft disorder characterized by node-like swellings along the shaft where the cuticle has split and frayed, causing the hair to break easily at those points.

• Usually caused by excessive heat styling, chemical over-processing, or mechanical damage.
• Appears as whitish nodes or thickened points along an otherwise normal strand.
• Treatment focuses on reducing damage—trimming affected areas and using protective/reconstructive products.

Memory trick: Nodosa = 'knots on the shaft' that snap under stress.

Cal/OSHA requires that all emergency exits remain unobstructed and accessible at all times to allow rapid evacuation during emergencies.

• Exits must be free of storage, furniture, or equipment
• Applies to all workplaces including salons
• Blocked exits are a common citation during safety inspections

Memory trick: Never block the exit — it's the salon's lifeline in an emergency!

When a predisposition test is positive, the client is allergic to aniline derivative dyes and must never receive that product; the reaction should be documented and safe alternatives offered.

• Positive test = confirmed allergy, do not proceed
• Document reaction on the client record card
• Offer non-aniline derivative alternatives
• Refer to a physician if reaction is severe

Memory trick: Positive test = a red STOP sign 🚫 — never use that dye again.

The practice of designing work tasks, tools, and posture to reduce physical strain and prevent injury during repetitive movements.

• Prevents repetitive strain injuries (e.g., carpal tunnel)
• Involves posture, seating, and workstation height
• Applies to long periods of manicuring, cutting, or standing

Memory trick: Bend the chair, not your back.

The active growth phase of the hair cycle when the hair is firmly attached to the papilla, making it the ideal time for hair removal services.

• Hair is actively growing and nourished by blood supply
• Best phase for waxing/tweezing for longest regrowth delay
• Followed by catagen and telogen phases

Memory trick: A-C-T: Active, Changing, Tired — Anagen grows, Catagen transitions, Telogen rests.

A highlighting method where sections of hair are isolated on foil to control processing and prevent bleed onto surrounding hair.

• Allows precise control of fine or thick sections
• Foil heat can also boost processing speed
• Common patterns: weave, slice, or babylights

Memory trick: Foil = a little pocket that isolates the strand from the rest of the world

Products from shared jars or tubs must be removed with a clean, disinfected spatula, scoop, or pump rather than fingers to prevent cross-contamination between clients.

• Applies to creams, waxes, and gels in tubs
• Fingers introduce bacteria and oils into shared product
• Use disposable or disinfected tools for each client

Memory trick: Fingers stay out — use a spatula scoop, not a finger poke!

A perm wrapping technique winding hair from ends to scalp with overlapping wraps, standard for hair up to shoulder length.

• Produces tighter curl at ends, looser at scalp
• Used for shorter to medium-length hair
• Rod is parallel to the base section

Memory trick: 'Croquignole Coils from the Corners (ends)' toward the scalp

The predictable sequence of color changes hair passes through as melanin is lightened during the bleaching process.

• Sequence: black > brown > red-brown > red > red-orange > orange > yellow-orange > yellow > pale yellow
• Reflects breakdown of eumelanin then pheomelanin
• Darker natural levels start further back in the sequence

Memory trick: Big Brown Rabbits Ran Right Over Your Yard (Black-Brown-Red-brown-Red-Red-orange-Orange-Yellow-orange-Yellow).

EPA-registered disinfectant solutions must be changed at least daily and immediately if visibly dirty, cloudy, or diluted to maintain effectiveness.

• Cloudy or discolored solution indicates reduced potency.
• Debris in solution can shield pathogens from contact.
• Manufacturer instructions on the product label also dictate replacement frequency.

Memory trick: 'Cloudy means change it now' — never trust a dirty-looking solution.

Round bacteria (cocci) that grow in grape-like cluster formations, commonly causing abscesses, boils, and pustular infections.

• Cluster arrangement resembles grapes
• Cause localized skin infections/abscesses
• Contrast with streptococci (chains) and diplococci (pairs)

Memory trick: 'Grapes cluster, chains link, pairs dance' — Staph=grapes, Strep=chains, Diplo=pairs.

The outermost layer of the epidermis composed of dead, keratinized cells that protect the skin and are continuously shed and replaced.

• Also called the horny layer
• Made of keratin protein for waterproofing
• Shed through natural desquamation

Memory trick: 'Grandma Gives Loving Care' = Germinativum, Granulosum, Lucidum, Corneum (plus Spinosum)

The hair's ability to absorb moisture/chemicals, determined by cuticle condition, directly affects how quickly perm solution penetrates and thus processing time.

• Resistant/low porosity = longer processing time
• Porous/damaged hair = shorter processing time
• Always perform a strand/test curl to confirm timing

Memory trick: Porous hair is a thirsty sponge—it soaks up chemicals fast, so pull it out sooner.

A petroleum-based cream applied to the scalp, hairline, and ears before hydroxide relaxer application to prevent chemical burns.

• Applied before relaxer, not to hair strands
• Protects sensitive skin areas from caustic pH
• Standard step in relaxer safety protocol under Title 16 practices

Memory trick: 'Base cream = Body armor before the burn'

A written Cal/OSHA-mandated safety program every California employer must maintain, covering hazard identification, correction, and employee training.

• Required for virtually all California employers, including salons
• Must be in writing and accessible to employees
• Includes hazard assessment, correction procedures, and training records
• Cal/OSHA inspectors can request the IIPP during any inspection

Memory trick: IIPP = 'I Identify, Prevent Problems' — hazards found, fixed, and documented.

Waxing over or near an active skin infection such as a cold sore (herpes simplex) is contraindicated due to risk of spreading the infection.

• Cold sores are caused by herpes simplex virus
• Waxing can spread virus to other skin areas
• Service should be postponed until lesion heals
• Applies to any open sore, rash, or active infection

Memory trick: Cold sore = 'contagious closed door' for waxing

Electrical implements must be wiped with an EPA-registered disinfectant rather than immersed, to prevent damage and electrical hazards.

• Never submerge electrical tools in liquid
• Wipe thoroughly, including crevices
• Non-electrical metal tools are fully immersed
• Applies to clippers, irons, dryers

Memory trick: Electrical tools = wipe don't dip, or you'll get shocked

Recording formulas, processing times, and reactions on client record cards creates a legal reference that protects the client and cosmetologist and informs future services.

• Documents formulas and processing times used
• Notes any adverse reactions
• Serves as legal protection and future reference

Memory trick: 'Write it down, cover the ground' — records protect everyone.

California law requires disinfection of implements with an EPA-registered hospital disinfectant for the proper contact time; full sterilization is not mandated for standard salon tools.

• Sterilization kills all life forms including spores; not required in CA salons
• Disinfection kills most pathogens but not necessarily spores
• UV cabinets are for storage of already-disinfected tools, not disinfection itself

Memory trick: CA salons 'disinfect,' hospitals 'sterilize' — don't confuse the two!

The angle at which a razor blade is held against a hair strand directly controls how much hair is removed; flatter angles remove less, steeper angles remove more.

• Blade angle controls degree of taper/thinning
• Steeper angle removes more bulk
• Improper angle can over-thin or damage hair ends

Memory trick: Steeper angle, sharper bite — more hair leaves the strand.

The visible, whitish, half-moon-shaped portion of the matrix at the base of the nail plate.

• Also called the 'half-moon'
• Its color comes from matrix thickness blocking underlying pink nail bed
• Most visible on the thumb

Memory trick: Lunula = 'lunar' moon shape at the nail's base.

A negative patch test shows no skin reaction after 24-48 hours, indicating the client is not sensitized to the product and the color service may proceed.

• Required before every new aniline-derivative color application
• Test site checked after 24-48 hours
• No redness/itching/swelling = negative = safe to proceed

Memory trick: 'Clear skin, clear to go' — no reaction means proceed.

A contagious fungal infection causing gray, scaly, circular patches and hair loss on the scalp; requires refusal of service and physician referral.

• Highly contagious fungal infection
• Presents as scaly circular patches with hair loss
• Cosmetologists must refuse service and refer to a physician

Memory trick: Ring around the scalp — Ringworm means refuse and refer!

The hair's ability to stretch and return to its original length without breaking, indicating the strength of internal protein bonds.

• Wet healthy hair stretches up to 50% of its length
• Dry healthy hair stretches about 20%
• Poor elasticity signals over-processing or damage
• Tested by gently pulling a single wet strand

Memory trick: Elasticity = a rubber band snapping back healthy.

HIV is a bloodborne virus transmitted through blood/body fluid exposure, not casual contact; standard precautions protect against it for all clients regardless of disclosed status.

• Not spread by touching skin, hair, or air
• Cannot legally refuse service based on HIV status alone
• Standard precautions apply to every client, symptomatic or not

Memory trick: HIV hides in blood, not in handshakes.

A heat spike is the burning sensation felt during gel curing caused by an exothermic polymerization reaction, most often from applying product too thickly.

• Thin, even layers reduce heat spike risk
• Client can remove hand briefly and reinsert if burning occurs
• Proper technique includes capping thin layers, not one thick coat

Memory trick: Thick gel = quick heat

A haircut created by projecting hair sections at approximately 180 degrees (straight up and over the head's curve), producing layers that are shorter at the crown and longer at the perimeter.

• Uses ~180-degree projection over the head's curvature
• Shortest layers at crown, longest at perimeter
• One of the four basic haircuts, contrasted with uniform layers at 90 degrees

Memory trick: 180 degrees = pulled all the way over, like flipping hair over a rainbow.

Clients with latex allergies require latex-free, hypoallergenic adhesives for strip lash or extension services to avoid allergic contact reactions.

• Latex-based adhesives can trigger allergic dermatitis
• Always ask about allergies during consultation
• Latex-free formulas are widely available for sensitive clients

Memory trick: 'Latex-free keeps eyes allergy-free.'

The silicone rod size used during a lash lift determines the tightness of the resulting curl; smaller rods create tighter curls, larger rods create softer curls.

• Small rod = tight, dramatic curl
• Large rod = soft, subtle curl
• Rod choice should match lash length and desired look

Memory trick: 'Small rod, small circle, big curl' — the smaller the rod, the tighter the curl.

Formaldehyde-releasing keratin treatments require local exhaust ventilation and SDS-guided PPE to protect against respiratory and eye irritation.

• Formaldehyde is a known irritant and carcinogen at high exposure
• SDS lists permissible exposure limits and required PPE
• Local exhaust ventilation captures fumes at the source, better than general ventilation
• Repeated daily exposure increases health risk for stylists

Memory trick: Capture fumes at the source before they capture your lungs.

Lash lift solutions rely on breaking disulfide bonds in natural keratin hair; synthetic lash extensions do not respond, so extensions must be removed before a lift.

• Lift chemistry only works on natural keratin structure
• Performing over extensions risks trapping chemicals and damaging natural lashes
• Extensions should be fully removed before scheduling a lift

Memory trick: Synthetic won't lift — remove the extensions first, or risk a rift.

California law requires disinfection (EPA-registered hospital disinfectant immersion) for salon implements, not the higher standard of sterilization used in medical settings.

• Sterilization kills all life forms including spores; not required in CA salons.
• Disinfection kills most pathogens and is the legal minimum.
• Autoclaves are optional equipment some salons choose to use but are not mandated.

Memory trick: 'Disinfect, don't sterilize' — the salon standard stops one level below hospital-grade sterilization.

Single-celled, animal-like microorganisms; some species are parasitic and cause disease in humans.

• Not classified as bacteria, fungi, or viruses
• Some cause diseases like amoebic dysentery
• Rarely a salon infection-control concern but part of microorganism taxonomy

Memory trick: 'B-F-V-P': Bacteria, Fungi, Viruses, Protozoa — four pathogen families.

A color category with large pigment molecules that coat the cuticle layer and are removed with one shampoo.

• No developer or peroxide needed
• Lasts only until next shampoo
• Cannot lighten hair, only adds color on the surface

Memory trick: Think 'T-S-D-P': Temporary Shampoos out, Semi Stays a bit, Demi Deposits longer, Permanent Persists

A condition, such as impetigo, that prohibits performing a cosmetology service due to risk of spreading infection.

• Impetigo shows honey-colored crusted lesions
• Highly contagious bacterial infection
• Service must be refused and client referred to a physician

Memory trick: 'Honey-crust = Halt the service' for impetigo

The hardened keratin structure that forms the body of the nail, extending from the matrix to the free edge, resting on the nail bed.

• Composed of translucent keratin
• Attached to nail bed but not fused to matrix
• Grows continuously from the matrix

Memory trick: Plate = the plate you file on top of the bed.

Applying color only to new hair growth near the scalp during subsequent color services to avoid overlapping onto previously colored hair.

• Prevents overprocessing and breakage
• Avoids banding/line of demarcation
• Typically done every 4-6 weeks as new growth appears

Memory trick: New growth only - don't repaint what's already painted.

The irreversible chemical process by which hydroxide relaxers convert disulfide bonds into lanthionine bonds, permanently straightening hair.

• Occurs with sodium, lithium, and guanidine hydroxide relaxers
• Bonds cannot be rebuilt, unlike thio relaxer bonds
• Requires careful strand testing due to permanence

Memory trick: 'Lanthionization = Lasting change, no going back'

A V-shaped point in the hairline at the center of the forehead, considered a natural hair growth pattern.

• V-shaped point at the front hairline
• Can affect styling and part placement
• Distinct from cowlicks and whorls

Memory trick: Widow's peak points down like an arrow to a heart.

Alkaline permanent waves use ammonium thioglycolate at a pH of about 9.0–9.6, causing hair to swell and process without added heat.

• Faster processing than acid waves
• No heat required, unlike exothermic/acid waves
• Can be harsher on damaged or fine hair due to higher pH

Memory trick: 'Alkaline is Nine-point-something, No heat needed'

A percussion massage movement involving tapping, slapping, or hacking to stimulate circulation.

• Most stimulating of the massage movements
• Used briefly to invigorate, not relax
• Contrast with gentle effleurage and kneading pétrissage

Memory trick: Tapotement = 'tap it' — tapping and slapping to wake up circulation.

Cutting hair with no elevation (0 degrees) produces a one-length, blunt haircut where all strands fall to the same weight line.

• 0 degrees = no elevation, hair cut at natural fall
• Produces a solid, weighted perimeter line
• Basis for the blunt/one-length haircut

Memory trick: Zero elevation = zero layers = one blunt line.

Ozone-generating devices may supplement footbath sanitation but cannot replace the CA-mandated cleaning and EPA-registered hospital disinfectant procedure.

• EPA-registered hospital disinfectant use is still required
• Cleaning logs must still be maintained
• Ozone is a supplement, not a substitute

Memory trick: 'Ozone helps, but doesn't replace the mop and log.'

Clients using oral isotretinoin (Accutane) have thinned, fragile skin, making waxing services contraindicated due to risk of tearing or scarring.

• Effect can persist up to 6 months after stopping medication
• Tweezing or threading are safer alternatives
• Always ask about recent medication use during consultation

Memory trick: Accutane thins skin — wax spins risk in.

A non-contagious skin disorder caused by loss of melanocytes, producing white, depigmented patches on the skin.

• Not contagious, safe to service
• Caused by loss of pigment-producing melanocytes
• Patches may appear on hands, face, or hairline

Memory trick: VitiligO = 'O' for outline of white patches, safe to service.

Clients with poor circulation or uncontrolled diabetes are at higher risk for skin damage and delayed healing, making waxing a contraindication on affected areas.

• Poor circulation slows wound healing
• Diabetic skin may be more fragile and prone to injury
• Cosmetologist should recommend alternatives or physician consultation
• Applies especially to lower legs and feet

Memory trick: Poor circulation = 'slow-healing zone' — avoid waxing

A guideline that moves as the haircut progresses, with each cut section serving as the guide for the next; used for layered and graduated haircuts.

• Moves section by section through the haircut
• Common in layered and graduated designs
• Contrasts with the fixed stationary guideline

Memory trick: Traveling guide 'travels' along like a train through each section.

Bacteria are classified into three basic shapes: round (cocci), rod-shaped (bacilli), and spiral (spirilla).

• Cocci: round, can cluster (staph) or chain (strep)
• Bacilli: rod-shaped, cause tetanus/tuberculosis
• Spirilla: spiral/wavy, cause syphilis/Lyme-type diseases

Memory trick: Cocci = Circles, Bacilli = Bars, Spirilla = Springs

California requires nonporous, multi-use implements to be fully immersed in an EPA-registered hospital disinfectant for at least 10 minutes (or longer per label instructions).

• Implements must be cleaned of debris before disinfecting
• Disinfectant must be EPA-registered and hospital-grade
• Store dry, disinfected tools in a clean, covered container

Memory trick: Ten full minutes — no shortcuts on the clock.

California requires cosmetology license applicants to be at least 17 years old, along with meeting educational and training hour requirements.

• Minimum age: 17 years
• Also requires 10th grade education or equivalent
• Must complete required training hours before exam eligibility

Memory trick: Seventeen candles on the license-eligibility cake.

The resting phase of the hair growth cycle, lasting about 3-4 months, during which the hair is dormant before shedding.

• Follows the catagen phase
• Hair is dormant, not growing
• About 10-15% of scalp hairs are in telogen at any time

Memory trick: TELogen = TELL it to rest before it falls.

A condition where hair is exposed to reducing lotion too long or at too high strength, breaking down excessive disulfide bonds and causing mushy, weak, overly elastic hair.

• Signs: mushy texture, excessive stretch, no snap-back
• Caused by too much time, strength, or heat during processing
• Stop processing immediately and rinse thoroughly if detected

Memory trick: Overprocessed hair is like overcooked spaghetti—mushy and won't hold its shape.
